Why nation, has Steve Colbert been such a great success? Since he left The Daily Show in 2005 to host a spin-off series, The Colbert Report and hasn't looked back since., The Colbert Report is a daily outrageously brilliant spoof on the of personality-driven political opinion shows such as The O'Reilly Factor.

Since its debut, the Colbert Report has been a hit, establishing itself as one of Comedy Central's highest-rated series, earning Colbert three Emmy nominations and an invitation to perform as featured entertainer at the White House Correspondents' Association Dinner in 2006. Colbert was named one of Time's 100 most influential people in 2006.
